where \(\mathbf {z}_i=\mathbf {z}(u_i)\) . Thus, standard statistical software for generalized linear models can be used to obtain the estimates. This fact is implemented in the \(\mathtt {spatstat}\)  \(\texttt {R}\)  package by \(\texttt {ppm}\)  function with option \(\texttt {method="mpl"}\)  [1]}.
